The present invention relatesto roller bolsters adapted for use inlumber trucks and similar vehicles and more particularly to combinedbolsters and stake pockets forsuch 8 vehicles. i

The object of the invention is to provide a simplifiedandimproved-bearing support in a roller bolQter of this descriptionwhichis. at the same time particularly adapted for a 10 stake support, and isstronger and cheaper to build than previous constructions.

WVith this object in view the main feature of the invention consistsinutilizing in a bolster. as a roller bearing andstake support, an angleiron hav ng vertical and hor zpntal faces slotted and fitted across the"end of the usual supporting channel irons in such a manner that thehorizontalfalce rests on the channel irons and acts to carry the ma orpart of the load which centers on the roller bearing carried on thevertical face, and forms at the same time a broad base to re; sist theoutward strainjot the stakes. A bolster constructed in this manner hasthe further advantage that the parts when fitted together areself-locking and form a structure of great strength and durability.

The various features of the invention consist also in the devices,combinations, and arrangement of parts hereinafter described andclaimed, and together with the ad vantages to be attained thereby willbe readily understood by those skilled in the art from the followingdescription taken in connection with the accompanying drawings in whichFig. .1 is a view in elevation of one embodiment of the invention in alumber truck showing only so much of the construction as is necessary toillustrate the connection of the present invention tl'ierewith. Fig. 2is an elevation, partly in section, of the parts shown in Fig. 1 lookingfrom the right. Fig. 3 is a plan view of the same parts, the stakesockets being left empty. Fig. 4 is a perspective view showing a portionof the bolster and the stake supports.

The combined roller bolster and stake support disclosed by the drawingsincludesa roller and a bed or cradle in which the roller is mountedextending transversely of the truck, and equipped with stake sockets,one on each side of the roller bearings.

The roller is indicated at 6, and two paral lel channels irons one oneach side of the roller forming the sides of the bolster cradle or bedare indicated at 8., A portion of one of the sills or beams forming partof the truck chassis by which the bolsters are usually supported isindicated atlO.

The ends of the bolster consist of angle iron cross pieces whichserve tosupport the rollenbe-arings 12 and the upright stakes 14, each crosspiecehaving a horizontal side 16 and a vertical side 18. Slots 20 arecut'in the vertical side 18 through whichthe lateral beams 8 projectinto contact with the under surface of the horizontal member 16. Bolts22 fasten the channel irons and cross pieces rigidly. together making abolster 01"". simple and at the same time unusually sturdyiconstruction.

. The stakesymay supported by sockets attached to the angle cross piecesin any convenient manner. In the present construction, apertures 24luive been cut inthe horizontal negro receive the stakes 1a with theedges or flaps Qtibcnt downward mast as barbstoholdthe posts inposition.The vertical side or face 18 of the cross plece'car ries the rollerbearing 12 and brackets 30 positioned beneath the apertures 24 to serveas additional supports for the stakes.

It is contemplated that a lock will be provided for the roller and theend of the trunnion 32 of the roller is squared to receive a hand leverso that the load may be easily moved in loading and unloading.

The invention having been thus described, what is claimed is:

1. A roller bolster and stake support for a lumber truck having, incombination. a roller, two transverse parallel sill-s one on eachside-of the roller and two angle iron cross pieces to support the rollerand stakes comprising vertical surfaces slotted to receive the sills,and horizontal surfaces to rest on the sills projecting through theslots and forming additional support for the vertical surfaces.

2. In a lumber truck the combination with a supporting frame of a rollerbolster and stake support comprising a roller, roll er bearings, stakesockets, two transverse parallel sills one on each side of the roller,and two angle iron cross pieces to support the roller bearings and stakesockets having vertical faces through which the sills are projected andcarrying the roller bearings and stake sockets, and horizontal faces to"rest on the sills for supporting the vertical faces.

3. In a lumber truck the combination with a supporting frame of a rollerbolster and stake support comprising a roller, two transverse parallelsills one on each side of the roller, two angle iron cross pieces to support the roller and stakes having vertical faces through which the sillsare projected and horizontal faces to rest on the sills for supportingthe vertical faces and roller bearings and stake socketscarried onthevertical faces of the cross pieces.

4:. A combination roller bolster and stake support for a lumber truckhaving, in combination, a roller, two transverse parallel sills one oneach side of the roller, two angle iron cross pieces having verticalsides slotted to receive the sills and horizontal sides with aperturesto receive the stakes and arranged to rest on the sills, roller bearingsmounted on the vertical sides of the cross pieces, and stake socketsmounted on the vertical sides to receive the butt-s of the stakes.

5. A combination rollerbolster and stal: support for a lumber truckhaving, in combination, a roller, two transverse parallel sills one 011each side of the roller, two cross members having face-s insubstantially horizontal and vertical planes, the horizontal faceshaving contact with and being secured to the transverse parallel sills,roller bearings mounted on the cross members, and stake sockets formedin the cross members.

6. A combination roller bolster and stake support for a lumber truckhaving,in combination, a roller, two transverse parallel sills one oneach side of the roller, two cross members having faces in substantiallyhorizontal and vertical planes, the horizontal faces having contact withand being secured to the transverse parallel sills, roller bearingsmounted on one of the faces of the cross members, apertures in thehorizontal faces for the stakes and stake sockets cooperating with theapertures to receive the stakes. 7. A combination roller bolster andstake support for. a lumber truck having, in combination, a roller,bearings for supporting the roller, two transverse parallel sills one oneach side of the roller, and two angle iron cross members having facesin substantially horizontal and vertical planes, the horizontal faceshaving contact with and being secured to the transverse parallel sills.

8. A combination roller bolster and stake support for a lumber truckhaving, in combination, means for supporting the stakes, a roller,bearings for the roller, two trans verse parallel sills one on eachside'of, the roller and two angle iron cross pieces ar-h ranged withtheir horizontal faces in contact with and secured to the transverse parallel sills. In testimony whereof I have name to this specification.
